AI Research Tools
Research tools help find, read and summarise sources. The single most important feature is whether the tool shows you where a claim came from, because a confident summary with no citation is worse than useless for anything that matters.
Good tools in this category make verification easy - linked sources, quoted passages, clear marking of what was inferred rather than found. That is the difference between a research assistant and a plausible-sounding guess.
What to check before you commit
- Citations that link to the actual source, not just a title
- Whether it tells you when it could not find something
- Coverage - which databases, papers or sites it can actually reach
- Export to a reference manager if you are writing something formal
